defense in depth

defense in depth definition - computer

Using multiple systems to resist attackers. For example, if an external firewall is breached, an internal intrusion detection system can sound an alarm. If systems are breached and data can be stolen, keeping all vital records encrypted on disk and encrypted during transmission prevents attackers from using it even if they get it.
